But algebraic expressions having more than two terms are collectively known as polynomials
Important points about Polynomials:
A polynomial can have many terms but not infinite terms.
Exponent of a variable of a polynomial cannot be negative. This means, a variable with power - 2, -3, -4, etc. is not allowed. If power of a variable in an algebraic expression is negative, then that cannot be considered a polynomial.
The exponent of a variable of a polynomial must be a whole number.
Exponent of a variable of a polynomial cannot be fraction. This means, a variable with power 1/2, 3/2, etc. is not allowed. If power of a variable in an algebraic expression is in fraction, then that cannot be considered a polynomial.
Polynomial with only constant term is called constant polynomial.
The degree of a non-zero constant polynomial is zero.
Degree of a zero polynomial is not defined.
